摘　　要：针对广东电网现有自动发电控制(AGC)电厂负荷分配方式的局限性,提出了基于实测煤耗的调度中心AGC电厂负荷优化分配方法,考虑了包括调节速率、临界负荷、机组备用在内的多种约束条件,并采用动态规划算法进行求解,在满足电网控制安全性的前提下实现了AGC电厂负荷分配的经济性。文中详细描述了AGC电厂负荷优化分配系统的总体架构、数学模型、求解算法、负荷优化分配流程等相关内容。实际应用表明,与传统的按容量分配机组负荷的方式相比,电厂负荷优化分配方法可以有效降低电厂总煤耗,提高经济效益。In view of the limitations of load distribution for the automatic generation control （AGC） power plant in Guangdong power grid, an optimal load distribution method based on real-time coal consumption is presented. By taking into account a variety of constraints including the regulation speed, critical load points and reserve, the problem is solved with the dynamic programming algorithm and economy of load distribution for AGC power plant is realized on the premise of satisfying the safety of power grid control. The overall architecture, mathematical model, solution algorithm and allocation process for the optimal load distribution system are described in detail. The actual system is being applied in Guangdong power dispatching center. Comparison with the traditional load distribution method shows that the proposed method can effectively reduce coal consumption of the power plant and improve economic returns.
